Dr. Allen Sills, the NFL's Chief Medical Officer, spoke directly about the electromagnetic field controversy during a behind-the-scenes tour of Levi's Stadium with ABC7's Dustin Dorsey.
"I am not aware of anything in the sports medicine literature that supports an association with the injury. In fact, we use electrical stimulation to treat a lot of injuries as a rehab modality. With that being said, we're always open minded."
